Can a VPN protect IoT devices? The short answer: Yes.

The Internet of Things, or IoT can be made up of everything from connected tablets, laptops, and smartphones to cameras, vehicles, and sensors. Securing the communications between these devices is critical. OpenVPN can help. Most Zero Trust Network Access (ZTNA) solutions are built around a human logging into a browser or app — which leaves unattended, always-on IoT devices out in the cold. OpenVPN takes a different approach, extending the same Zero Trust principles to devices that can never complete an interactive login.

IoT and Zero Trust Network Access (ZTNA):
Identity for Devices That Can't Log In

Zero Trust Network Access (ZTNA) assumes no device is trustworthy by default, human or otherwise, and grants access only after identity is verified. The problem most ZTNA platforms run into is that they were designed for people: a camera, sensor, or point-of-sale terminal can't complete a browser-based login or respond to an MFA prompt.

OpenVPN closes that gap with a client-based, certificate-driven architecture built for devices, not just users. Every IoT device and router is issued a digital certificate-based identity and authenticated mutually before a connection is ever established — the same never-trust, always-verify model applied to your workforce, extended to hardware that was never designed to prove who it is.

Never trust, always verify

Every IoT device authenticates with a digital certificate before any connection is established; nothing is trusted based on network location alone.

Enforce least privilege access

Isolate IoT devices into their own overlay networks so a compromised sensor or camera can't reach anything beyond what it needs.

Prevent lateral movement

A compromised device stays contained instead of becoming a launchpad into the rest of your network.

Built for unattended devices

Auto-login credentials and mutual certificate authentication support always-on IoT connections that most ZTNA and SASE platforms, designed around human/browser logins, don't account for.

IoT devices are one of the clearest examples of the “non-human identity” problem Zero Trust has to solve, alongside service accounts and, increasingly, AI agents. See how this fits into a complete Zero Trust Network Access (ZTNA) architecture on our Zero Trust Network Access (ZTNA) use case page, or read the technical detail on our IoT security feature page.
